. -METAL STRUCTURE.

Specification of Letters Patent. Patelited Sept. 30, 1913- Application filed November 27, 1911. Serial No. 662,567.

To all whom it may concern:

' joist.

v length.

Be it .known that I, WILLIAM L. CALD- WELL, a citizen of theUnited States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Metal Structures; and I do hereby declare that the following is a full, clear, and exact description of the same, such" as will enable others skilled in. the art to which it pertains to make and use the same:

The present invention has relation to metal structures designed to be usedin "buildings and is calculated to take the place and be used instead of .wood studding and The objects of the present invention are, first to provide a metal structure especially designed to; hold in proper position the usual plaster board, or similar material, second, to provide means for securing the metal studding or structure in position with reference to. the building. These objects, together. with other" objects, readily apparent to those skilled in the art, I attain by the constructionillustrated in the accom-- panying drawings, although my invention, may be embodied'in a variety of other forms the construction illustrated being chosen by way of example. 7 In the accompanying drawings Figure is a perspectiveview of the metal structure, studding or joist. Fig. 2 is a transverse section, showing two metal structures or studs in cross section and illustratmg the;

plaster boards properly connected, the plaster boards being shown in section.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings. i

In the accompanying drawing, '1 represents a portion of one stud or joist or metal structure are provided with,the, integral angled flanges 3, which flanges are for the purpose ofproviding suitable backing or rests for the plaster boards or their equivalents and upon which the backs of the plaster boards or their equivalents are seated. The structure 1 is also provided upon its longitudinal edges with bendable tangs 4, which are located between the an: gled flanges 3.

In Fig. 1 I have illustrated a metal strucstructure, the longitudinal edges of the ture provided with angled flanges extended .in opposite directions from the body of the structures." This construction being neoes sary when plasterboards or their equivalents are to-be connected as illustrated in Fig. 2, but itwill be understood that when plaster boards or their equivalents are to be connected upon one edge' of the structure only, the angled flanges 3' are extended from one side of the structure .only, but in any eventthe bendable tangs 4 are to be located alternately with reference to the'flan'ges 3'.

For thepurposeof adjustingthe length of the stud, jo1st or metal structure so as to provide" means for. connecting the ends; of the same the adjustable connecting plate or head 5 is provided, which connecting plate or head is providedwith the elongated slot .6, through which the clamping bolt 7 is passed. The plate or head 5 is connected with the angled flange 8, which flange is for, the purpose of making the proper connectionb'ymeans of nails or their equivalents. 1 For the purposejof increasing the rigidity'ofthe stud, joist or structure 1,.the bodyportion is corrugated. as illustrated or more specifically provided with the curved portion, 9. In. the drawings, I have illustrated, .a single curved portion, but it will be understood that more than one curved portion may be provided ifdesired, as the only object is to stiffen the structure.

In use the desired number of studs, joist or metal structures are placed in proper relative position and in the position usually occupied by the ordinary wood studdlng and joist; The, plaster boards or their equivalents are placed in proper relative position and in such a position, that is to say, placed.

against the angled flanges after which the bendable'tangs 4 are bent into the position illustrated in Fig. 2. It will be understood that by bending the tangs 4 in opposite di- V rections, the plaster boards or their equivalents will be held snugly against the flanges formed of such a 3. In use the plaster boards 2 are formed of such a size that they can be placed in proper position with reference to their supports. It will be understood that if in the event plaster boards should be used they should be redetermined size that a single board will ll the space between any two studs,'joist or metal structure, or the studs, joist or metal structures should be so spaced with reference to each other that the vertical edges of the plaster boards or their equivalents will be adjacent each other at or near the-parallel edges of the studs, joist or metal structure, so that by bending the bendable tan s in opposite directions the vertical" edges 0 two plaster boards will be heldat the places: where the studs, joist or metal structures are located. In the drawings I have illustrated the adjustable plate or-head 5 located at the top or upper end of the stud or metal structure, but it will be understood that a duplicate head or plate may be located at the bottom or opposite end of the stud as desired. The structure is preferably formed of sheet metal and I of a width equal to the width and lengths of the flanges and bendable tangs. The flanges and tangs are produced by cutting the body portion for a distance equal to the length of the flanges and bendable tangs, thecuts being made at right angles to the length of the body portion.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is-

1; A metal structure of the character described formed from sheet metal and comprising an elongated main body portion provided at its longitudinal edge with transverse slits forming integral relatively broad flanges and integral relatively narrow bendabletangs, said flanges bent at substantially right angles to the main body portion and said tangs normally lying in the same plane with the main body portlon. 2. A studding of the class sisting of a metallic strip provided with-a series of oppositely disposed slits extendingalong the edges thereof, and forming a series of wings along said edges, certain of said wings being bent 'to extend at approximately right angles to -the body of said studding, a portion of said bent wings extending in a direction from the body of the studding op- 'posite to that direction in which the redescribed, conmainder' ofsaid bent wings extend, the re- WILLIAM L.
